HENRY M. FRANKENFIELD ATTORNEYS United States Patent O 3,280,662 BAREN Henry M. Frankenfieid, Audubon, NJ., assignor to Hunt Manufacturing Co., Philadelphia, Pa., a corporation of Pennsylvania Filed July 12, 1965, Ser. No. 471,193 8 Claims. (Cl. 81-1) This invention relates to a baren useful for rubbing paper against an ink printing block to form a hand print.

The baren of this invention has numerous marked advantages. In the rst instance, there is very little friction between the baren and the paper being rubber which tends to insure that the paper will not inadventantly be misaligned. Further, in contrast to' heretofore known barens, the baren of this invention is long wearing. In addition, the baren is provided with a quality of resiliency which promotes the application of the desired pressure against the paper.

These and other objects of the invention will become apparaent on reading the following description in conjunction with the drawings in which:

FIGURE l is a front elevation of a baren in accordance with the invention;

FIGURE 2 is a side elevation of the baren of FIGURE 1;

FIGURE 3 is a top plan view of the baren of FIG- URE 1;

FIGURE 4 is a vertical section taken on the plane indicated by the line 4--4 in FIGURE 1; and

FIGURE 5 is a perspective View illustrating the employment of the baren of FIGURE 1.

A baren 2 in accordance with the invention has a frame 4 molded from a synthetic resin (plastic) but which may equally well be of any other suitable material, such as wood. Frame 4 has a bottom portion 6 with a substantially flat external face 8. Frame 4 Ihas a flange 10 and integral upstanding handle support members 12 and 14 which support a handle 16 secured thereto by means of screws 18, 18.

A circular resilient pad 22 of, for example, rubber, overlies the outer face 8 of bottom portion 6 and is substantially coextensive therewith. Pad 22 is adhered to face 8 by a suitable adhesive indicated at 24 (FIGURE 4).

A sheet 26 of a flexible fluorocarbon or fluorohalocarbon resin overlies the outer face of pad 22. Sheets of polytetrafluoroethylene (TFE), fluorinatedethylene propylene (FEP) and chlorotrifluoroethylene (CTFE) are illustrative.

Sheet 26 has a peripheral portion 28 which extends about the lower portion of flange in overlaping relationship. A metal ring 30 overlies this portion 28 and secures the sheet 26 to frame 4 by virtue of peened por- 3,280,662 Patented Oct. 25, 1966 ICC tions 32 which together with the adjacent portions of sheet 26 enter into frame 4, as best seen in FIGURE 4.

The use -of baren 2 is illustrated in FIGURE 5. A printing block 36 having a design 38 cut into it is coated with ink in the conventional manner, the ink not being shown. A sheet of paper 40 overlies block 36. Baren 2 is moved about over the upper surface of sheet 40 with the application of moderate pressure to press sheet 40 against block 36 to cause the transfer of the desi-red design shown at 42 onto sheet 40.

It Will be understood that the above described embodiment of the invention is simply by way of specific illustration and is not intended to be limited.

What is claimed is:

1. A baren comprising a frame having a substantially flat bottom face,

a resilient pad adjacent to the said bottom face and substantially coextensive therewith, and

a flexible sheet of a fluorocarbon or fluorochalocarbon resin overlying the outer face of the pad,

said pad and said sheet being secured to said frame.

2. A baren in accordance with claim 1 in which the resin is polytetrafluoroethylene.

3. A baren in accordance with claim 1 in which the resin is fluorinated ethylene propylene.

4. A baren in accordance with claim 1 in which the resin is chlorotrifluoroethylene.

5. A baren comprising a frame having a substantially flat bottom face,

a resilient pad adjacent to the said bottom face and substantially coextensive therewith, and

a sheet of a flexible fluorocarbon or fluorohalocarbon resin overlying the outer face of the pad and having a portion thereof extending above the lower portion of the frame in overlaping relationship a ring overlying said portion of the sheet and means securing the ring to the frame.

6. A baren in accordance with claim 5 in which the resin is polytetrafluoroethylene.

7. A baren in accordance with claim 5 in which the resin is fluorinated ethylene propylene.

8. A baren in accordance with claim 5 in which the resin is chlorotrifluoroethylene.
